Once a year, the hallowed Grimbolt Monster can be seen slinking around on Monster Mountain. Though grounded in Earth and Electric Elements, historical records attribute an additional quality to the Grimbolt, an otherworldly sense that only permits the monster's arrival around All Hallow's Eve. When spooked, Grimbolt Monsters will zap into a skeletal form.

Breeding Information

The Grimbolt Monster can be purchased for or bred by using Earth and Electric elements in the Breeding Den. Hybrids may be needed for successful breeding. See the chart below for some suggested combos.

Although hatching a mythic version of the Grimbolt Monster is random, your best chance to get one is to breed 2 Grimbolt Monster's together. You must have the Mythic Cave on your island in order to get a mythic. You can also use boost to better your chances.

If you used one of these combos, please +1 to the Successful Hatches column. If your combo is not here, please add it accordingly and put a 1 in the Successful Hatches column.

If you do add, please only increase the number for that combo by 1. The Successful Hatches column goes by per-person, not per-instance.

Instead of social combo adding, please increase the main element combo.

Monster Evolution
